Roger Clemens’ former catcher with the Toronto Blue Jays testified Wednesday that he had seen vitamin B12 “shots lined up ready to go” for players, a claim also made by Clemens and for which he was charged with obstructing Congress.

A government witness testified Tuesday that Brian McNamee said he had injected pitcher Roger Clemens with human growth hormone and had saved syringes, part of a prosecution attempt to dispel defense suggestions that McNamee fabricated those claims to avoid going to jail.
